Simplify algebraic expression y+3y-2

Mathematics
1 answer:
Tcecarenko [31]3 years ago
5 0

Answer:

the answer is 4y-2

Step-by-step explanation:

To simplify any algebraic expression you need to add liketerms.

In this equation, the liketerms are y and 3y.

3y+y= 4y

We are left with 4y-2; we cant go any further, because 4y and -2 are not liketerms.

Between which two consecutive whole numbers does the root of 59 lie​
IrinaK [193]

Answer:

Step-by-step explanation:

¿Entre que números naturales consecutivos se encuentra cada raíz?

Bueno en este caso debes empezar por el 1 en adelante, pero solo sucede en números impares consecutivos. Solamente debes sumar 1,3,5,7,9,11,13,15,17,19 ..... en adelante, y en cada suma de cada sucesión encontraras un cuadrado. Ojo solo sumando en orden, tampoco sumarás 3+9, ya que te dará 12 y 12 No tiene raíz.

1+3=4,√4=2

4+5=9, √9=3

9+7=16, √16=4

16+9=25, √25=5

25+11=36, √36=6

36+13=49, √49=7

49+15=64, √64=8

64+17=81, √81=9

81+19=100, √100=10

............................................................................................................

A SI CONSECUTIVAMENTE SIEMPRE OBTENDRÁS CADA RAÍZ  

¿Entre que números naturales consecutivos se encuentra cada raíz?

R= En los número impares consecutivos, comenzando por el 1 en adelante.

Freshman geometry!!! number for please help!!
BARSIC [14]

Option C:

The perimeter of the rhombus is 100 inches.

Solution:

AC = 30 inches, BD = 40 inches

In rhombus, diagonals bisect each other at right angles.

AE = CE = 15 inches

BE = ED = 20 inches

In ΔAED, ∠E = 90°

Using Pythagorean theorem,

AD^2=AE^2 +ED^2

AD^2=15^2 +20^2

AD^2=225+400

AD^2=625

AD^2=25^2

Taking square root on both sides, we get

AD = 25 inches

In rhombus, all sides are equal in length.

AD = DC = CB = BA = 25 inches.

Perimeter = AD + DC + CB + BA

                 = 25 + 25 + 25 + 25

                 = 100 inches

The perimeter of the rhombus is 100 inches.

Option C is the correct answer.

Someone please help me
Anika [276]

Answer:

A

Step-by-step explanation:

Given

a = \frac{1}{x} - \frac{1}{y} = \frac{y-x}{xy} ← as a single fraction

Thus

\frac{1}{a} = \frac{1}{\frac{y-x}{xy} } = \frac{xy}{y-x} → A
